PORTLAND, Ore. 
Gerald Wallace had 28 points, his most with the Trail Blazers, and Portland routed the Washington Wizards 111-76 on Tuesday night.

LaMarcus Aldridge had 22 points before sitting for the fourth quarter, and Nicolas Batum added 22 points and 12 rebounds for the Blazers, who are jockeying for playoff position in the Western Conference as the season winds to a close. Portland moved within a game of Denver for the sixth spot, and a game up on seventh-place New Orleans.

Jordan Crawford had 12 points for the Wizards, who dropped their seventh straight on the road to fall to just 1-32 away from home.

Portland led by as many as 38 points, and the starting lineup scored all but 20 of the team's points.

Washington was without guard Nick Young, the team's top scorer with an average of 17.7 points per game. Young has missed four games because of a bruised left knee.

The Blazers played without center Marcus Camby, who twisted his right ankle in Portland's 84-80 loss to the Los Angeles Lakers on Sunday.

The Wizards kept the Blazers within reach early, but Portland began to extend the margin midway through the second quarter. Wesley Matthews' putback dunk made it 48-37, and the Blazers led 62-45 at halftime.

Wallace's alley-oop dunk off a pass from Brandon Roy made it 89-57 in the third.

The Blazers acquired Wallace in a trade with the Bobcats just minutes before the Feb. 24 NBA deadline. Portland sent centers Joel Przybilla and Sean Marks, forward Dante Cunningham and two conditional first-round picks to Charlotte.

Wallace, who also rested in the fourth quarter, was one point short of his season high.

Washington was coming off a 98-92 victory at home over New Jersey. The stop in Portland was the first in a five-game road trip.
